      WHEREAS the Trustee, on behalf of the Trust, has agreed, on the terms and
conditions contained herein, to purchase from the Depositor the Specified

Second Assignment and Assumption.

      (c) On and as of the date hereof, Sunset represents and warrants to the

amended solely with respect to the Specified Mortgage Loans by inserting the
following:

      "(ix) have a Stated Principal Balance, after deduction of the principal
      portion of the Monthly Payment due in the month of substitution, not in

                                       3

<PAGE>

      Qualified Substitute Mortgage Loan would not adversely affect the REMIC
      status of any REMIC created under the Pooling and Servicing Agreement or
      would not otherwise be prohibited by the Pooling and Servicing Agreement."

      (b) With respect to the Specified Mortgage Loans, "Eligible Investments"
shall have the meaning of "Permitted Investments" as defined in the Pooling and
Servicing Agreement.

      (c) Section 1 is hereby amended by inserting the following new definition:

      "Rating Agency": Each of Standard & Poor's, a division of The McGraw-Hill
      Companies, Inc., Fitch Ratings and Moody's Investor Services, Inc., as
      applicable.

      (d) Notwithstanding any provision in the Agreement to the contrary, the
parties to the Agreement hereby agree that, in connection with any prepayments
of the Specified Mortgage Loans in a Mortgage Pool (as defined in the Pooling
and Servicing Agreement), the Servicer shall contribute from its own funds, to
the extent that such contributions do not exceed the aggregate Servicing Fees
for the Specified Mortgage Loans in such Mortgage Pool, any shortfall in the
interest component thereof such that one month's interest shall be deposited to
the Custodial Account as defined in the Agreement.

      (e) Subsection 11.04(i) of the Agreement is hereby amended and restated in
its entirety as follows:

      "(i) with respect to each Principal Prepayment, an amount (to be paid by
      the Servicer out of its own funds) which, when added to all amounts
      allocable to interest received in connection with the Principal
      Prepayment, equals one month's interest on the amount of principal so
      prepaid for the month of prepayment at the applicable Mortgage Loan
      Remittance Rate; provided, however, that the Servicer's aggregate
      obligations under this paragraph for any month shall be limited to the
      total amount of Servicing Fees actually received with respect to the
      Mortgage Loans by the Servicer during such month."

      (f) The fifth paragraph of Subsection 11.12 of the Agreement is hereby
amended and restated in its entirety as follows:

      "With respect to any REO Property, the deed or certificate of sale shall
      be taken in the name of the Purchaser, or its designee. The Trustee's name
      shall be placed on the title to such REO Property solely as the Trustee
      hereunder and not in its individual capacity. The Servicer shall ensure
      that the title to such REO Property references the Agreement and the
      Purchaser's (or its designee's) capacity thereunder. Pursuant to its
      efforts to sell such REO Property, the Servicer shall either itself or
      through an agent selected by the Servicer protect and conserve such REO
      Property in the same manner and to such extent as is customary in the
      locality where such REO Property is located and may, incident to its
      conservation and protection of the interests of the Purchaser, or its
      designee, rent the same, or any part thereof, as the Servicer deems to be
      in the best interest of the Purchaser, or its designee, for the period
      prior to the sale of such REO Property. The Servicer shall prepare for and
      deliver to the Purchaser, or its designee, a statement with respect to
      each REO Property that has been rented showing the aggregate rental income
      received and all expenses incurred in connection with the maintenance of
      such REO Property at such times as is necessary to enable the Purchaser,
      or its designee, to comply with the reporting requirements of the REMIC
      Provisions. The net monthly rental income, if any, from such REO Property
      shall be deposited in the Certificate Account no later than the close of
      business on each Determination Date. The Servicer shall perform the tax
      reporting and withholding required by Sections 1445 and 6050J of the Code
      with respect to foreclosures and abandonments, the tax

                                       4

<PAGE>


      reporting required by Section 6050H of the Code with respect to the
      receipt of mortgage interest from individuals and any tax reporting
      required by Section 6050P of the Code with respect to the cancellation of
      indebtedness by certain financial entities, by preparing such tax and
      information returns as may be required, in the form required, and
      delivering the same to the Purchaser, or its designee, for filing.

      In the event that the Purchaser, or its designee, acquires any Mortgaged
      Property as aforesaid or otherwise in connection with a default or
      imminent default on a Mortgage Loan, the Servicer shall dispose of such
      Mortgaged Property as soon as practicable in a manner that maximizes the
      Liquidation Proceeds thereof, but in no event later than three years after
      its acquisition by the Purchaser, or its designee. In that event, the
      Purchaser, or its designee, shall have been supplied with an Opinion of
      Counsel to the effect that the holding by the Purchaser, or its designee,
      of such Mortgaged Property subsequent to a three-year period, if
      applicable, will not result in the imposition of taxes on "prohibited
      transactions" of any REMIC as defined in section 860F of the Code or cause
      any REMIC to fail to qualify as a REMIC at any time, the Purchaser, or its
      designee, may continue to hold such Mortgaged Property (subject to any
      conditions contained in such Opinion of Counsel) after the expiration of
      such three-year period. Notwithstanding any other provision of this
      Agreement, no Mortgaged Property acquired by the Purchaser, or its
      designee, shall be rented (or allowed to continue to be rented) or
      otherwise used for the production of income by or on behalf of the
      Purchaser, or its designee, in such a manner or pursuant to any terms that
      would (i) cause such Mortgaged Property to fail to qualify as "foreclosure
      property" within the meaning of section 860G(a)(8) of the Code or (ii)
      subject any REMIC to the imposition of any federal, state or local income
      taxes on the income earned from such Mortgaged Property under Section
      860G(c) of the Code or otherwise, unless the Servicer has agreed to
      indemnify and hold harmless the Purchaser, or its designee, with respect
      to the imposition of any such taxes."

      (g) The first sentence of Subsection 11.15 of the Agreement is hereby
amended and restated in its entirety as follows:

      "Statements to the Purchaser. Not later than the 10th calendar day of each
      month (or, if such 10th day is not a Business Day, the following Business
      Day), the Servicer shall forward to the Master Servicer in hard copy and
      electronic format a statement, certified by a Servicing Officer, setting
      forth (a) the amount of the distribution made on such Remittance Date
      which is allocable to principal and allocable to interest; (b) the amount
      of servicing compensation received by the Servicer during the prior
      calendar month; (c) the aggregate Stated Principal Balance and the
      aggregate unpaid principal balance of the Mortgage Loans as of the last
      day of the preceding month; and (d) the paid through date for each
      Mortgage Loan. Such statement shall also include information regarding
      delinquencies on Mortgage Loans, indicating the number and aggregate
      principal amount of Mortgage' Loans which are either one (1), two (2) or
      three (3) or more months delinquent and the book value of any REO
      Property, or such other mortgage loan level data as agreed upon by the
      Servicer and the Master Servicer, and monthly reports substantially in the
      form of Exhibit 9 attached hereto."

      (h) Subsection 11.19 of the Agreement is hereby amended and restated in
its entirety as follows:

      "Annual Statement as to Compliance. (a) The Servicer shall deliver to the
      Purchaser and the Master Servicer, on or before March 1st each year
      beginning March 1, 2004, an Officer's Certificate stating that (i) a
      review of the activities of the Servicer during the preceding calendar
      year and if performance under this Agreement has been made under such
      officer's supervision,

                                       5

<PAGE>

and (ii) to the best of such officer's knowledge, based on such review, the
Servicer has fulfilled all its obligations under this Agreement throughout such
year, or, if there has been a default in the fulfillment of any such obligation,
specifying each such default known to such officer and the nature and status
thereof and the action being taken by the Servicer to cure such default.

(b) For so long as the Mortgage Loans are being master serviced by a master
servicer in a securitization transaction (the "Master Servicer"), by the later
of March 1 or 30 days prior to the date on which the Form 10-K is required to be
filed with the SEC of each year (or if not a Business Day, the immediately
preceding Business Day), an officer of the Servicer shall execute and deliver an
Officer's Certificate to the Master Servicer for the benefit of such Master
Servicer and its officers, directors and affiliates, certifying as to the
following matters:

      (i) Based on my knowledge, the information in the Annual Statement of
      Compliance, the Annual Independent Public Accountant's Servicing Report
      and all servicing reports, officer's certificates and other information
      relating to the servicing of the Mortgage Loans submitted to the Master
      Servicer taken as a whole, does not contain any untrue statement of a
      material fact or omit to state a material fact necessary to make the
      statements made, in light of the circumstances under which such statements
      were made, not misleading as of the date of this certification;

      (ii) Based on my knowledge, the servicing information required to be
      provided to the Master Servicer by the Servicer under this Servicing
      Agreement has been provided to the Master Servicer;

      (iii) I am responsible for reviewing the activities performed by the
      Servicer under the Servicing Agreement and based upon the review required
      by this Servicing Agreement, and except as disclosed in the Annual
      Statement of Compliance and the Annual Independent Public Accountant's
      Servicing Report submitted to the Master Servicer, the Servicer has, as of
      the date of this certification fulfilled its obligations under this
      Servicing Agreement; and

      (iv) I have disclosed to the Master Servicer all significant deficiencies
      relating to the Servicer's compliance with the minimum servicing standards
      in accordance with a review conducted in compliance with the Uniform
      Single Attestation Program for Mortgage Bankers or similar standard as set
      forth in the Servicing Agreement.

(c) The Servicer shall indemnify and hold harmless the Master Servicer and its
officers, directors, agents and affiliates from and against any losses, damages,
penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments and other costs and expenses arising out of or based upon a breach by
the Servicer or any of its officers, directors, agents or affiliates of its
obligations under this Section 11.19 or the negligence, bad faith or willful
misconduct of the Servicer in connection therewith. If the indemnification
provided for herein is unavailable or insufficient to hold harmless the Master
Servicer, then the Servicer agrees that it shall contribute to the amount paid
or payable by the Master Servicer as a result of the losses, claims, damages or
liabilities of the Master Servicer in such proportion as is appropriate to
reflect the relative fault of the Master Servicer on the one hand and the
Servicer on the other in connection with a breach of the Servicer's obligations
under this Section 11.19 or the Servicer's negligence, bad faith or willful
misconduct in connection therewith."

      (i) Subsection 11.20 of the Agreement is hereby amended and restated in
its entirety as follows:

                                       6

      member of the American Institute of Certified Public Accountants to
      furnish a statement to the Purchaser and the Master Servicer to the effect
      that such firm has, with respect to the Servicer's overall servicing
      operations, examined such operations in accordance with the requirements

      period, its obligations under Subsections 11.19 or 11.20 which failure
      continues unremedied for a period of fifteen (15) days after the date on
      which written notice of such failure, requiring the same to be remedied,
      shall have been given to the Servicer by any party to this Agreement or by
      any master servicer responsible for master servicing the Mortgage Loans
      pursuant to a securitization of such Mortgage Loans;"
